Bedankt aan de organisatoren! Ondanks dat ik maar een uurtje kon blijven, was het plezant en heb ik veel kunnen bijleren. Zeker voor herhaling vatbaar!

Ik ben ook van plan om te komen. Ik kom met het openbaar vervoer vanuit Leuven dus spijtig genoeg kan ik mijn RepRap niet meenemen, maar ik ben wel benieuwd naar de andere zelfbouw machines die er te zien zullen zijn.

Can't you adjust the flow rate in your slicer as well?

Kunnen jullie wat meer info geven over het verschil tussen
* PLA Premium Frosty White -- 26.45 euro voor 1kg
* EcoPLA - White -- 32.95 euro voor 0,75kg
Waarom zou ik voor het duurdere EcoPLA kiezen?
PS: Jullie hebben een heel mooi aanbod maar het is een beetje jammer dat de verzendkosten naar Belgie aan de hoge kant zijn (15,73 euro voor een spool van 1kg).

@bobc I just committed a new development version of tltgen that includes a CSV import feature. I don't have any binaries out yet (because the application is still rather unstable), but you can check out the source code from Google Code and compile it yourself, if you're interested. Let me know if you have any problems, I'll try my best to help...

Experimental
Have you checked out the source from Google code lately? If so, you've probably noticed that I've been working on a new implementation. It uses C++ instead of C, which makes properly structuring the code much easier. It also has a GUI instead of only a command line interface.
If you send me an example text file, I could take a look to see if I could implement an import feature for this type of f

I created a script to extrude a brim around the edge of the print bed before starting the actual print (helps with priming the extruder).

Linux 64 and 32 bits. Other platforms are on my todo-list.
Print a brim close to the edge of the print bed at the start of the print, to give the extruder a chance to get started properly before getting to the actual print.

Have you seen the assembly instructions at ? The PTFE lining tube should be 37mm, so it should go 7mm into the brass part. As you've already mentioned, some people even need to glue the PTFE lining to the brass part to stop leaking. Also, I've heard that it is very important to really *crush* the brass/copper parts when attaching the heater block to the tube and the nozzle.
I've very curious ab

I'm also interested in this hot-end but it doesn't look as firm as V3. The assembly guide warns about crushing the thin stainless steel barrel. Also, I do not see it in the arcol webshop, so we can't seem to order it...

I've been working on Yet Another RepRap Firmware (Yarf) and I've just released version 0.1.
Yarf's key features include:
* True linear acceleration and deceleration
* A lookahead algorithm (based on grbl)
* Includes Matt Roberts' advance algorithm
* PID temperature control
* Runs on common 8-bit MCU's such as the ATmega644p and ATmega1284p
* Direct support for thermistor tables generated by tltg

Firmware - experimental, borrowed, and future
Hi Liam,
I don't have the Eagle files online yet, but I'm planning to publish them somewhere in the near future.
I'll send you the most recent version of the eagle files through a PM today or tomorrow.
Note that I've also written my own firmware for this board. It's currently still in development but for me it works great. I'm planning to make a version 0.1 release of it this month. It can be

Hello everybody,
I've created an open source utility for generating more accurate thermistor lookup tables for your favorite firmware. The utility is named 'tltgen' and can be downloaded here.
Some information:
The lookup tables generated by tltgen are based on either the beta equation (1/T = 1/T0 + 1/B*ln(R/R0)) or the Steinhart-Hart equation (1/T = A + B*ln(R) + C*(ln(R)^3)). The latter provi

Mmh well it might be interesting to be able to plot values obtained by measuring a real controller side by side with the values of a simulated controller. That would obviously require some communication between this application and the firmware, which is not implemented right now. I'll look in to this in the next couple of days.

Firmware - experimental, borrowed, and future
Yes, absolutely. You can download the source code from the google code project page (currently only using git but I might upload a zip-file containing the source code of the 1.0 release) and add some Java code to 'simulate' the behaviour of your firmware. This actually comes down to porting the algorithm used in your firmware to Java, which should be straightforward.
You will also need to make s

Firmware - experimental, borrowed, and future
Hello everybody,
I've created a small open-source Java application for simulating the temperature evolution of a virtual heating element. The temperature of the virtual heater is measured by a virtual thermistor. The power applied to the heating element can be controlled by various controller algorithms, which try to maintain a certain target temperature.
This simulator can be used to compare

Firmware - experimental, borrowed, and future
Yes, you are absolutely right! I forgot the MS1 external pulldown. I'm updating the schematic and board to fix this and I'll also make the heater traces even wider.
Thanks for the check-up, it may have saved me a lot of trouble!
Edit: I've added the updated board and schematic to the opening post.

Absolutely, the board is already partly based on the Gen 7 electronics, with some modifications.

Hello,
I've designed my own custom electronics PCB for my future prusa mendel build. The choice for a custom board as opposed to the many existing electronics is based primarily on the following:
* I want a board that's easy to etch myself * I want a board that doesn't require an ATX PSU * I just think it's fun to design my own electronics
So this is what I made:
Board:
Schematic:

I assume this will also work on a prusa mendel, i.e., when using bushings instead of bearings?
